Lance Cabo 50 electrical issues plus no spark

There is a trigger coil, to tell the CDI when to "fire" and the exciter coil which has only two wires and it energizes the CDI. I suspect your ignition switch is grounding the CDI. Chase the kill wire down and make sure it isn't grounded when you are trying to start/run. Here ya go, get ur multimeter and diagnose, test points will be voltages at the trigger coil, the exciter coil, and coil. It's actually a pretty simple system https://www.buggydepot.com/tech-cent...uide-no-spark/ Let us know what you find

Okay, I know its been awhile... but here we are. The ignition switch is fine, I had forgot a jumper wire I had setup. Once setup properly, ignition switch works as expected. Since then, i replaced the stator and pickup. No change. I tested all types of things from all types of videos. Everything seems to test fine. Ultimately, my cdi is getting power from the ignition switch as it should, and I can get some readings from pickup coil when cranking. Whether I have the seat compartment switch attached or not or have it turned on or off or not, I get power to the starter. The killswitch on right handle can be on or off, and still gets power to starter. For anyone who doesn't know, this DC cdi is powered from the ignition directly from the battery, and there is no killswitch pin on the cdi, the killswitch 'grounds out' the coil or cdi to dissallow spark. 'Grounding out' a circuit is something I don't fully understand. So at this point I convinced myself that it must be the RH switch. Ordered one and installed. Still no spark. To date, I have replaced the plug, coil, stator, pickup, ignition, cdi, and killswitch.
I'm losing my mind over this. At this point, I believe it must be either the seatcompartment killswitch, or a bad wire. Additionly, the right blinkers don't work. I had read somewhere that someone had a DC motorcycle that wouldn't start because the headlight bulb was bad. I'm running out of ideas.
